Application filed November 16, 1921 Serial Nol 515,462.

To all whom it may concern:

Be it known that I, GEORGE ENKLER, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Ventilators, of which the following is a specification.

This invention relates to ventilating apparatus and has particular reference to those used in combination with a window, and the main object is to provide a Ventilator which can be inserted in a window casing in such manner that a window may be closed down upon the ventilator, leaving no openings for insects to fly through.

Another object is to provide means for locking the ventilator in the casing so that the wind. or tampering therewith, will not disturb the same.

These and other objects, which will be come more apparent as the description progresses, are attained by the novel construction and arrangement of parts hereinafter described in which similar characters of reference refer to like-named parts in the drawing, in which Figure 1 is a front elevational view of a window having my ventilator in position at its bottom.

Figure 2 is a front elevation of the venti lator.

Figure 3 is a similar elevation, but seen from the air inlet side.

Figure 4 is a sectional elevation taken on the line 4-4 of Figure 3.

Figure 5 is a section taken through the hinged panel, on the line 55 of Figure 6.

Figure 6 is a side elevation of the hinged panel showing the locking rods.

Referring more in detail to the drawing, the numerals 10 and 11 represent the upper and lower window sashes respectively, which are slidably secured in theusua-l type of window casing 12.

A panel composed of members 13 and 14, the latter connected to the former by hinges 15, is fitted into the window casing after the lower window sash 11 has been raised. Panel 13 has a rectangular opening 16 protected by the wire mesh screen 17, by which dust particles and other impurities are filtered from the air as it passes therethrough. A chute 18, having a tapered bottom 19 and sides 20, is secured to the opposite side of panel 13 by semi-circular moulding strips 21 and is provided to deflect the filtered air stream upwardly through the open end of the chute 18. 4

In order to insert the ventilator between the side guides ofa window casing they looking bolt 22, slidably mounted in bearings 23 formed on the surface of plate 25, is moved out of engagement with yoke 24 on the panel 13, thereby permitting member 14 to be rotated about hinges until the length of the ventilator is short enough to pass the pro jecting guides.

The panels 13 and 14 can then be straight ened, after which the bolt 22 can be again engaged with yoke 24.

Simultaneously with the locking movement of the bolt 22, levers 26 movable in slots 81 extending from a recess 34 in the back of the member 14 are caused to rotate about the pivot pins 28, by a pin 27, the latter. being fixed to the underside of the bolt 22, and engaging the slots 29 formed in the coincident ends of levers 26. The op posing ends of levers 26 have slots 29' in which are engaged pins 30 integral with the slide rods 31. Figure 2 that, as bolt 22 is pushed into the locked position, the ends 32 of the slide rods will be extended into recesses 33' in the easing 12 thereby securing the ventilator in the desired position in the window casing.

Thus it is apparent trom From the foregoing description it will be seen that a novel device for this purpose has been disclosed in the preferred embodiment, but it is not desired to restrict the de-' tails to the exact construction thereof, it be ing obvious that minor changes in the size, proportions, arrangementand details thereof may be made without conflicting with the scope of the invention as defined by the claims hereto appended.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is l 1. In combination with a window ventilator having a pair oi. panels hinged to each slide bolt on the latter panel, a yoke meme vber on the other panel aligned with the slidev 7 bolt and adapted to receive said bolt, said,

slide bolt when engaging the yoke being adapted to retain both ventilator panels in alignment, and means for emending the slide rods beyond the edge of the panel when looking said slide bolt in the yoke.

2. In combination with a Window ventilator having a pair of panels hinged to each other, means for securing the same Within a Window casing comprising a yoke member on one panel adjacent the hinged end, a sliding bolt mounted on the other panel adjacent the hinged end and adapted to engage said yoke When the panels are aligned, a pin secured to said bolt,'pivoted levers having i slotted ends engaging said pin horizontalflw ing When said locking bolt engages the yoke 15 member.

' In Witness whereof I affix my signature.

GEORGE ENKLER.
